A masked man points a weapon as he speaks in this still image from a handout video obtained on January 4, 2016 from a social media website which has not been independently verified. Britain was on Monday examining the Islamic State video showing a young boy in military fatigues and an older masked militant who both spoke with British accents. The propaganda video, which could not be independently verified, also shows the killing of five men accused of spying for the West. (Photo by Reuters/Social Media)
